It is considered the cultural center of Bali, where you will discover the art and spirit ofBaliand learn about Balinese religion through paintings, dance, and other art forms. You could drink a beer while watching a local band perform, but most people come here for the cultural appreciation.Nusa LembonganThis tiny island off the coast of Bali is where many people miss their journey plans, but it is a must-see, It is the perfect place to stay for a couple of nights, The roads are not good, but the island itself is so beautiful and quiet.SanurSanur is an especially relaxing beach town. It's close to the airport and Kuta. It's also the starting place to explore Nusa Lembongan.KutaThebeachofKutais great for surfing. It is crowded and you won't get far without someone trying to get you to rent a surfboard or buy something. The main town is a mixture of market stands and shopping malls containing the biggest brands, from Zara to Ralph Lauren. The familiarity of the western style shops and restaurants won't give anyone too much of a culture shock.1. Which place are you probably advised to experience Balinese culture?A. Nusa Lembongan.B. Sanur.C. Ubud.D. Kuta.2. What is special about Kuta?A. It is a beach town near the airport.B. It has a convenient transportation means on it.C. It is a shopping center and famous for surfing.D. It is a place where you can learn Balinese history.3. Where is the text probably taken from?A. An official document.B. A travel magazine.C. A science report.D. A history book.BHidden beneath the surface in the roots of Earths astonishing and diverse plant life, there exists a biological superhighway linking together the members of the plant kingdom in what researchers call the "wood wide web".The network is comprised of thin threads of fungus (真菌) that grow outwards underground up to a few meters from its partnering plant, meaning that all of the plant life within a region likely connected to one another. The partnership is beneficial for both parties involved, plants provide carbohydrates (碳水化合物) to the funguses and in exchange, the funguses aid in gathering water and providing nutrients to its partnering plant.A study conducted by Rensen Zeng of theSouthChinaAgriculturalUniversityfound that this also allowed for plants to warn one another of potential harm. The study showed Broad Beans used the fungal network to spy on one another for upcoming danger.Like our Internet, this fungal connectivity is also full of crime. Some plants, such as Golden Marigolds have been found to release poisons into the network to slow down the growth of surrounding plants in the fight for water and light. Other plants, such as the Phantom Orchid, do not have the chlorophyll (叶绿素) and must get the necessary nutrients from surrounding plants.Research suggests that animals such as insects and worms may be able to detect slight exchanges of nutrients through the network, allowing them to more easily find delicious roots to feed on; however, this has not been conclusively made clear in experimentation. The more we learn about this phenomenon, the more our understanding of the plant life of our planet will continue to change. Perhaps one day, we may be able to map out these complex networks entirely.4. What is the function of the first paragraph?A.To explain the aim of the web.B. To introduce the main topic.C. To give definition of diverse life.D. To show the importance of plants.5. The criminal behavior of plants can be seen as a way to________.A. compete for survivalB. gather more waterC. take in sunlightD. break natural rules6. What does the last paragraph suggest?A. Animals can also feed on the fungus.B. Nutrient exchanges are too slight to detect.C. No experiment can prove the phenomenon.D. More needs to be done to work out the network.7. Which can be the best title for the text?A. The Partnership between PlantsB. The Unknown Roots of the EarthC. The Superhighway Linking the PlantsD. The Mysterious Map Changing the WorldCWe have most friends at the age of 26 afterhaving spent the first quarter of our lives building up our friendship circle, new research has claimed.The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference."Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% todrift away fromchildhood friends.With growing pressure being put on friendship these days, it's important to make time for our friendship.8. How many friends can a 20-year-old college student make via Facebook?A. 22.B. 18.C. 12.D. 4.9. In Paragraph 5, the author is trying to tell the readers ________.A. how important making friends isB. school time is an important period to develop friendshipC. how much has been done to keep friendshipD. that friendship is not easy to keep10. The underlined phrase "drift away from" in Paragraph 6 means ________.A. make sense ofB. make up withC. feel sorry forD. lose touch with11. This passage is mostprobably taken from ________.A. a newspaperB. an advertisementC. a textbookD. Facebook or TwitterDA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”12. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.13. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA14. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible15. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effect第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

I, as a mother, was tired from the anger and her inability to communicate because of her slowed language development.As I accompanied her into the car, I felt desperate.

I didn’t interrupt. “See that climber.” He pointed to a wooden piece of playground equipment that looked like a rock wall. I nodded. “Well, every day since she started school, she’s tried and failed to make it to the top.” He took a breath. “And today she did it!”He expressed his joy just as he’d witnessed her conquering Mount Everest! “She cheered and celebrated! I wish I’d recorded it!” His words comforted me. My daughter had conquered her mountain.As she ran toward me. I recognized something I hadn’t before. I saw her perseverance(毅力). I saw her strength.

Ensure to look out for morris dancing. It is a folk dancing that dates back to the 15th centuryMen and women wearing old-fashioned clothing dance in the streets of towns and villages across the country during the holiday periods.Some groups carry heavy black sticks which they bash(敲击) against each other while they dance. Other groups wave handkerchiefs(手帕) in the air when they perform. The dances are usually performed near a pub so that when they are over, the dancers and audience can sing some traditional folk songs over a pint of beer. The festivities will often continue long into the night, by which point most people are too drunk to think about performing again!Morris dancing is a great English tradition but it’s facing a big crisis( 危机). As the years go by, fewer and fewer young people are joining morris dancing groups. The dancers are getting older and older and if nothing is done to change this trend, the tradition will die out within the next few decades.If you’ve ever had the fortune to see morris dancing, you may understand why teenagers aren’t rushing to sign up. Putting it clearly, it’s not exactly the coolest thing for an 18-year-oldto be doing! Why dress up in bells and funny clothes when you could be going clubbing? Or playing sport? Or doing anything else?However, it would be a great shame to lose such a fun part of England’s history and culture. It’s important to look after some traditions and customs especially when it’s something as harmless and happy as morris dancing. So here’s a toast(祝酒)to the next generation of would-be morris dancers!8．What can we learn about morris dancers?A．They sing songs about beerB．They beat each other with black sticks.C．They offer handkerchiefs to the audience.D．They usually drink beer after the performance9．What difficulty does morris dancing face?A．It may disappear in future B．All the dancers are too oldC．It is hard for people to learn.D．Nothing can be done to develop it. 10．What do the questions suggest in Paragraph 4?A．The young are busy with other things.B．The young think morris dancing is boring.C．The young have all kinds of interests in life.D．The young always like doing the coolest things.11．What does the author want to express in the last paragraph?A．Morris dancing brings fun to people.B．England has rich history and cultureC．Morris dancing should be passed down.D．Some traditions are harmless to be passed down.Shanghai residents passing through the city’s eastern Huangpu district in October might have astonished at an unusual sight: a “walking” building. An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors helpcontrol how the building moves forward.The Lagena Primary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building.In recent years, China’s rapid modernization has seen many historic buildings razed to clear land for skyscrapers and office buildings. But there has been growing concern about the architectural heritage loss as a result of destruction across the country.Shanghai has been China’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life. The city also has a track record of relocating old buildings. In 2018, the city relocated a 90-year-old building in Hongkou district, which was then considered to be Shanghai’s most complex relocation project to date.12．How did the primary school get moved?A．By reducing the weight of it.B．By using movable supports.C．By dividing it into several parts.D．By using robotic legs.13．What does the underlined word “razed” probably mean in Paragraph 5? A．Replaced.B．Burnt.C．Protected.D．Destroyed.14．What can we infer about the heritage preservation in China?A．The use of advanced technology leads to growing concern.B．Shanghai is the pioneer in preserving architectural heritage.C．A number of old buildings have been given new life.D．Many historic buildings will be relocated.15．What is the passage mainly about?A．New preservation campaigns are launched in China.B．New technology gives new life to historic buildings.C．A building in Shanghai “walks” to a new location.D．“Walking machine” makes heritage protection simpler.二、七选五People often want to simplify their lives. It is a lot of stress to have a complicated life, full of schedules, meetings, possessions, and so forth. Usually, a simpler life translates to lesslifestyle piece by piece.First, get rid of all the possessions you haven't used in the last year. If you haven't put a thing to use in one year, it is probably not worth keeping. 17 Put anything you haven't used in one year in that bag. Next, manage your social media and electronics usage. We usually spend more time on our devices than we imagine. These days, people can spend the majority of their days on social media and electronic devices. These all-in-one devices are great tools. 18On a deeper level, we can simplify our thinking. Most of our thinking is not necessary.19 If you do not want to go that far, try to ignore the thoughts that are not related to the present. A continuous stream of thoughts is not necessary. Sure, some planning should be done for the future, but there is no need to overthink.20 We can get rid of possession's that are non-essential, manage our social media and electronics usage, and also clean up our thinking so that we are more in the present and do not engage in unnecessary worry, or anxiety. All these things take energy and time, of which we have only have a limited amount.A．No thought is important.B．Get rid of electronic devices'C．So, how do we simplify our lives?D．Is planning our thoughts effort-making?E．Simplifying our lives is a complex task.F．But they should not become the main focus of our life.G．Get a big garbage bag and walk around your living space.三、完形填空Molai grew up in a tiny village in India.

2021届新高考模式八省高三名校新题分项汇编之书面表达--应用文写作【河北省2021届高三上学期10月联考】阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

It's getting hot. It's time to put on lighter clothes and open up the windows. I can't wait to do so. Yesterday, an unforeseen visit to the kitchen happened during the brief time we were out. Two daring sparrows (麻雀) had risked landing on our territory to enjoy the freshness in our sink and some other breadcrumbs (面包屑) on our kitchen counter.Actually, sparrows are everywhere. The tiny, gray -and brown birds are found on every continent except Antarctica, flying or jumping around cities, picking up leftover food on side-walks, and sometimes chasing with native bird species. These small creatures have adapted to living alongside humans- similar to pet dogs.When you come across such sudden callers, you are likely to sense it as an unwanted visitor into your comfort zone, or you might receive it as a lovely angel of life. I chose the second option, with no hesitation while my husband preferred driving them away. After all, I've never come to stop to feel the relationship with sparrows.I recalled when I was a little girl living in the city, I lived in an apartment with a flat roof viewed from our kitchen window. Every day my mom and I would go out to feed the sparrows. She taught me how to call them with a clicking sound she made with her tongue. I have loved sparrows ever since. So every day in my spare time, I can't stop observing and celebrating their dance from our window. I stuffed them with the leftovers on our tablecloth after every meal. And I have provided them with every kind of bases and stands of our house.Undoubtedly, they feel at ease in our backyard. And that has led them to gather up courage and slide into our kitchen, bedroom or even reading room. Perhaps because they have the feeling that we don' t consider them trouble makers, but friendly neighbors. But I am slightly worried about their droppings (粪便).注意:1.续写词数应为150左右;2.请按如下格式在答题卡的相应位置作答。

ANeed a fall fix? Try one from these great places.1. Mackinac Island, MichiganThe only way to reach this famed car-free island is by boat and ferry, and once visitors arrive, they’re attracted by the history, scenery and fall colors. “It’s a throwback to years past, a little town, and there’s a big state park as well,” Blackwell says. “You’re allowed to have boats all around the island.”2. Tellico Lake, TennesseeWith nearly 400 miles of shoreline, this waterway flowing out of the Great Smoky Mountains is largely unexploited, well-protected in its natural state. Fall visitors find a range of colors reflecting in the clean waters, says Blackwell, who vacationed in the area with his family as a child. “The thick forest there just allows you to see more greenery and wildlife.”3. Dillon Reservoir, ColoradoWith an hour from Denver, this lake is home to what claims to be the nation’s highest sailing club, at an altitude of more than 9,000 feet. Marinas in the towns of Dillon and Frisco make it easy to get out on the water and to see the bright yellows and golds of fall leaves. “People are surprised that there’s boating in Colorado, and you can see the mountains just before the snowfall,” Blackwell says.4. Lake Monroe, IndianaThe state’s largest lake is surrounded by more than 13,000 acres of protected forest and three recreation areas, making it an ideal place to see fall colors, particularly from oaks and the tulip poplar, the state tree. “It’s a gem （宝石）in southern Indiana,” says Blackwell, who grew up in the area. “There are lots of different activities: canoeing, kayaking and fishing.”A.It’s like a modern city.B.Visitors can’t take boats around it.C.Visitors can see various wildlife there.D.Visitors can’t go there by cars.22.Which is suitable for someone looking for an undeveloped place for vacation？A.Mackinac Island, MichiganB.Tellico Lake, TennesseeC.Dillon Reservoir, Coloradoke Monroe, Indiana23.What do the four places have in common?A.Blackwell once travelled there .B.They are all famous tourist destinations.C.They are surrounded by thick forests.D.Visitors can enjoy fall colors thereBWhen HarmonyOS, the Chinese self-developed operating system for Huawei mobile devices, was released on Aug 9, it quickly became a hot topic on social media. Many believe it not only represents the rise of the country as a tech power, but also shows respect to classical Chinese culture by naming the system “Hongmeng” in Chinese.“Hongmeng” is a classical word from Zhuangzi. In the ancient times of Chinese legend and myths (神话), “Hongmeng” was used to describe the original state of the universe before matter existed. For HarmonyOS, “Hongmeng” indicates the developers’ aim to make an innovative operating system, unlike any other.Besides “Hongmeng”, Huawei has also registered many of its products under the names of legendary creatures from Chinese myths. For example, the company’s Kirin mobile chip got its name after a lucky monster called “Qilin”. And its server chip is called “Kunpeng”, a creature that changed from a fish into a giant bird.Many Chinese internet users and media have praised Huawei’s use of these names, “as they stand for Chinese wisdom and anci ent people’s imagination and spirit of exploration”, Global Times noted.In fact, Huawei is not alone in using traditional culture for modern ventures. Ne Zha, the new film, also portrays traditional culture in a modern context. The movie is loosely based on the well-known work of classical Chinese myth The Investiture of the Gods. Earlier this month it became the biggest animated movie in China and was called “the glory of domestic anime(国产动漫)”.Indeed, the long history and splendid classic works have given China a profound culture. Myths and legends are the creative works of tremendous imagination. As Global Times put it, today by revisiting a modern context, “ancient myths has the power to inspire imagination in young people”. After all, imagination is the beginning of creation.224.What do we know about HarmonyOS?A.Its release raised a storm of objections.B.It is named after a creature in myth.C.It combines high technology and culture.D.It’s the best operating system.25.Which of the following best expl ains “innovative” underlined in Paragraph 2?A. creativeB. modernC. popularD. intelligent26. How do the public think of Huawei’s use of the names?A. Confused.B. Unexpected.C. Approving.D. Doubtful.27.What can be inferred from the last two paragraphs?A.The film Ne Zha is not adapted from myths.B.The film Ne Zha is a big hit.C.More businesses follow Huawei’s leadD.Ancient myths is a good choice for entertainmentCPeople who sleep fewer than six hours a night are more likely to die early, researchers in University of Warwickhave found in a recent study. They discovered that people who slept for less than six hours each night were 12% more likely to die before the age of 65 than those who slept the recommended six to eight hours a night.The researchers pointed out that previous studies had shown that the lack of sleep was associated with problems like heart disease and high blood pressure. However, the researchers also found that sleeping too much was linked to an early death. Those who slept for more than nine hours a night were 30% more likely to die early, as an article in the latest Sleep suggested. That directly contradicts another passage in the same journal last month suggesting that people who slept for ten hours or longer a night were more likely to live to 100. This was thought to be because people who lived into extreme old age were healthier and therefore slept better.However, the authors of the latest research contradicted this and suggested that long sleep was a sign of underlying illnesses such as depression and low levels of physical activity. Professor Francesco Cappuccio at the University of Warwick said: “While short sleep may represent a cause of ill-health, long sleep is believed to represent more an indicator of ill-health.”He also mentioned: “Modern society has seen a gradual reduction in the average amount of sleep people take, and this pattern is more common among full-time workers, suggesting that it may be due to social pressures for longer working hours. On the other hand, the worsening of our health is often accompanied by an extension of our sleeping time.”“Consistently sleeping six to eight hours per night may be good for health. However, whether to achieve the goal depends on various factors such as the environment as well as measures of public health aimed at favourable changes of the working environments,” Professor Francesco Cappuccio added.28.What did researchers in University of Warwickhave find?A.People who sleep fewer than 6 hours each night die before 65.B.Sleeping for more than 9 hours a night does good to one’s health.C.Six to eight hours’ sleep can be appropriate for people.D.People at an old age are healthier because they sleep longer.29.What is Professor Francesco Cappuccio most likely to agree with?A.Long sleep is what causes our health problems.B.Modern people sleep less because they work longer.C.Our health becomes worse because we sleep less.D.How long we sleep depends on our education.30.What did the researcher think may help people have proper sleep?A.Social pressure.B.Longer working hours.C.Extension of sleeping time.D.Changes of working environments.31.What can be the best title for this passage?A.How Long Should We SleepB.Longer Sleep Makes Better HealthC.Time to Sleep EarlyD.The Importance of SleepDImagine a school where self-awareness is celebrated, students are encouraged to solve maths problems by writing on the walls and applying learned lessons to real life is more important than homework. These are a few of the concepts that make Space of Mind School unique.Located in a home built in 1896 in Florida, US, the program serves students in grades 2 through 12 and will accept kindergarten students next year. It also offers an afterschool program for students who attend traditional schools, as well as evening programs for adults and educators and weekend events for families.There is a different atmosphere from that of a traditional school building. Tables and brightly colored walls are white boards. In the science room, students are studying climate changes at a weather station, while in the music room, a student is solving an equation(等式) with his academic coach while he connects music theory and maths.The daily schedule at the school also stands out. “We don’t assign boring or exhaust ing homework,” said Space of Mind founder and CEO Ali Kaufman. “Instead of homework, we ask that they go home and take a video of themselves applying a lesson they learned or cooking a meal for their family that they learned how to make at school.”For lunch, instead of traditional cafeteria dishes such as pizza, the school offers organic meals made out of products from local gardens and farms. “Our students also run a business at the Delraybusiness,” Kaufman said.“We are also the first school program in Florida to start and end each day with 15 minutes of meditation(冥想),” Kaufman said. “The positive results we have been seeing in the students from meditation are amazing. We are really about infusing social, emotional and creative skills with academic and life skills.”32.Space of Mind School _________________________.A.assigns no homework.B.urges students to use what they learn.C.teaches students to earn money in class.D.focuses on knowledge learning.33.What can be inferred from the last paragraph?A.Yoga enjoys great popularity in US.B.The practice of meditation is amazing.C.The meditation session lasts 15 minutes daily.D.The students benefit from meditation.34.The underlined word “infusing” in the last paragraph probably means_______.A. emphasizingB. checkingC. developingD. helping35.What is the text mainly about?A.What makes Space of Mind School outstanding.B.Why Space of Mind School is popular in US.C.How the after-class programs of Space of Mind School are organized .D.

He had broad shoulders and truly 22 the definition of the V body type. He was really a man with strength and endurance.John worked for some days, when there were no 23 and he was absolutely a hell of a great miner. However, the 24 day came, when I was ten; a terrible disaster 25 . Timber crossbars (木梁) were often used in mines to 26 the top. That day my father was working alongside John in the mine. A timber cracked suddenly and the loud cry of men was 27 . Hearing this, my dad and John rushed to the site of the 28 . There some miners were trapped; they felt 29 and depressed, either in shock or in prayer.In times of emergency, John began to rescue the miners without hesitation. He grabbed the timber and with a strong push applied all his 30 to it. In a seemingly impossible turn of events, the blocking moved. John 31 the timber and all the miners escaped, but in doing so, the wood structure was becoming further weakened, and John himself was trapped below in place of the miners.

七选五专题卷(一)(每篇10分钟)A(2020·山东青岛高三二模) In springtime,many Americans take on a major project: cleaning their homes from top to bottom.We often call this kind of work “spring cleaning”. Part of spring cleaning often involves clearing out clutter (杂物).We do away with things we no longer need.If we are to believe the many stories on Marie Kondo,the Queen of Clean,clutter adds unnecessary stress to our lives.Clutter is holding us back from our dreams and goals.1.An expert on the subject,Sabine Kastner of Princeton University,has been studying how the brain processes clutter for 20 years.The media,Kastner says,often writes about clutter in a very simple,black-and-white way: Clutter affects the mind and we need to clear it out.But it is much more complex than that.For starters,our brains are designed to deal with clutter.Very early in the development of our eyesight,we begin to group objects that we see.2.According to Kastner,there is not a one-size-fits-all solution.3. In fact,some people need to see their work.If something is carefully put away,to them it does not exist anymore.Out of sight,out of mind.For other people,objects can stimulate their creativity and give them ideas.4. Kastner notes that some people may get distracted by having lots of things around them.These people may need more organization and less clutter to work well.5. Whether the area is cluttered or clear—they work the same.And for others it may depend on the project.For administrative work,they might need a clear workspace.But for more creative projects,they may need many things around them.It is complex.A.But is it true?B.What is working and what is not?C.Some people do not care either way.D.This helps us to structure our environment.E.People need to be able to design their workplaces.F.The idea that an uncluttered workplace is better,is not universally true.G.However,other people are unable to work in a cluttered environment.语篇解读:主题语境——人与自我话题——杂乱的影响本文为议论文,一项研究表明,杂乱的工作环境对人的影响因人而异,并非所有的杂乱都是坏事。
